Abstract
A compact image reading apparatus such as a copier has a document table which can move reciprocatingly with respect to the top surface of its housing. A spiral spring is attached to the document table and as the user manually moves the document table from its initial position to a starting position for its operation, the spiral spring is wound up and stores energy as internal elastic energy. When the user releases the table, the spring releases its stored energy and the table moves across the top surface of the housing to effect the scan of a document set on the table.
